RESUMO
BACKGROUND: The incidence of anal cancer has been increasing in the United States. Smoking is a well-established risk factor; however, the impact of smoking on disease re-currence and outcome has not been well studied. The aim of this study was to assess the association between anal cancer recurrence and cigarette smoking. AIM: To investigate the relationship between cigarette smoking status and anal cancer treatment outcome. METHODS: The cancer registry from a single, community hospital was screened for patients with anal cancer between 2010 and 2021. The following characteristics were gathered from the database: Age; sex; cigarette smoking history; American Joint Committee on Cancer Clinical Stage Group; response to therapy; recurrence; time to recurrence; mortality; time to death; and length of follow-up. Patients were divided into the following groups: Current smokers; former smokers; and never smokers. SPSSv25.0 software (IBM Corp., Armonk, NY, United States) was used for statistical analysis. RESULTS: A total of 95 patients from the database met the screening criteria. There were 37 never smokers, 22 former smokers, and 36 current smokers. There was no difference between groups in regards to race or sex. There was no difference in the American Joint Committee on Cancer Clinical Stage Group between groups. The former smokers were significantly older when compared to never smokers and current smokers (66.5 ± 13.17 vs 57.4 ± 7.82 vs 63.7 ± 13.80, P = 0.011). Former smokers and current smokers had a higher recurrence rate compared to never smokers (30.8% and 20.8% compared to zero, P = 0.009). There was not a significant difference in recurrence between former smokers and current smokers. There was no difference in the mortality, non-response rate, or time to death between the groups. CONCLUSION: Our data contributes evidence that cigarette smoking status is associated with increased recurrence for patients with anal cancer.
RESUMO
BACKGROUND: A large proportion of patients with anorectal complaints are referred to colorectal surgeons with the label of hemorrhoids. OBJECTIVE: The purpose of this study was to review presenting symptoms and frequency of accurate diagnosis, as well as to analyze determinants of misdiagnosis to guide educational endeavors. DESIGN: This was a retrospective study. SETTINGS: The study was conducted at a tertiary care academic center. PATIENTS: The charts of patients referred to a colorectal clinic with the diagnosis of hemorrhoids from January 1, 2012, to January 1, 2017, were reviewed. MAIN OUTCOME MEASURES: The accuracy of the referring provider's diagnosis of hemorrhoids was measured. RESULTS: Review of charts identified 476 patients with the referral diagnosis of hemorrhoids. The most common presenting symptoms were bleeding (63%; n = 302), pain (48%; n = 228), and protrusion (39%; n = 185). Anal examination (ie, external inspection and/or digital internal examination) was documented in only 48%. The hemorrhoid diagnostic accuracy was 65% (n = 311). Among patients with incorrect hemorrhoid diagnoses (35%; n = 169), actual diagnosis was anal fissure (34%), skin tag (27%), and hypertrophied papilla (6%). One rectal and 2 anal carcinomas were found (0.63%). Compared with general practitioners, gastroenterologists had 86% higher odds of correct diagnosis (OR = 1.86 (95% CI, 1.10-3.10); p = 0.02), whereas the gynecologists had 68% lower odds of correct diagnosis at the time of referral (OR = 0.32 (95% CI, 0.10-0.80); p = 0.02). On multivariable analysis, referring specialty was not predictive of accurate diagnosis. Patients presenting with protrusion had 73% higher odds of accurate diagnosis (OR = 1.7 (95% CI, 1.1-2.7); p = 0.02), whereas patients presenting with pain (OR = 1.6 (95% CI, 1.1-2.5); p = 0.03) or pruritus (OR = 2.5 (95% CI, 1.2-5.0); p = 0.008) were more likely to be misdiagnosed. LIMITATIONS: This is a retrospective study. Not all of the charts contained all data points. The number of patients may limit the power of the study to detect some differences. CONCLUSIONS: A variety of anorectal complaints are diagnosed as hemorrhoids by providers who have initial contact with the patients. Educational programs directed toward improving physician knowledge can potentially improve diagnostic accuracy and earlier initiation of appropriate care. Presenting symptoms other than protrusion lead to higher rate of misdiagnosis by a referring physician. See Video Abstract at http://links.lww.com/DCR/A847.
